spring配置文件  加入  

    <!-- spring data redis -->
    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="usePool" value="true"></property>
        <property name="hostName" value="${redis.host}" />
        <property name="port" value="${redis.port}" />
        <!--  <property name="password" value=""/> -->
        <property name="timeout" value="${redis.timeout}" />
        <property name="database" value="${redis.default.db}"></property>
        <constructor-arg   ref="jedisPoolConfig" />
    </bean>


    <!-- 连接池参数配置 -->
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="${redis.maxActive}" />
        <property name="maxIdle" value="${redis.maxIdle}" />
        <property name="maxWaitMillis" value="${redis.maxWait}" />
    </bean>

    <!-- 配置redis模板,方便存取数据 -->
    <!-- <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">-->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory" />
    </bean>

pom.xml文件需要下载jar包

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>

    <dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>2.9.0</version>
    </dependency>

    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-redis</artifactId>
      <version>2.5.1</version>
    </dependency>

 建一个测试包在src下

 实现一些简单的功能：

Set  list    hash   sortedset   时间   操作字符串等
